Starch in the Paper Industry - ScienceDirect

Jan 01, 2009· In current practice, cationic starch products are widely used to improve the strength of paper. Cellulose fibers are capable of adsorbing up to 4–5% cationic starch. The addition of 0.5%–2% is often sufficient; further starch addition can adversely affect sheet formation due to charge reversion on fibers .

Paper and Pulp Waste | Hazardous Waste Experts

There are two main steps in the production of paper, pulping and bleaching. Pulping is the initial stage and the source of most of the pollution generated by paper industries (Ince, Cetecioglu, & Ince 2011). Pulp is a mixture of cellulose fibers and water and is used as a basis for all paper products (United States Environmental, 2012).
